[Rhodes22-list] Wind-induced noise in rigging/mast while docked

[Mary Lou Troy]

Hi Al,
We've occasionally heard the noise you describe 
with the boat in the slip and the wind coming 
from a certain direction. I think it's the wind 
playing the mast tube across the slot. I have not 
found a way to get rid of it. I'd be interested 
to hear what anyone else has to say. Several 
other boats in our marina do this but Fretless has her own identifiable moan.
